To (all. w/wnt it JIM/,1] concern:

Be it known that l, )lALON l. FLownns, a I citizen of the United States, resident of Lin 1 coln, in the county of Washington and State of Arkansas, have made it certain new and useful Invention in Electric 'linie Switch; and I declare the following to he will enable others skilled in the art to which it appertains to make reference being had to the accompanying drawings, and to letters or figures of reier- .ence marked thereon, \rlnch form a part of g this specification.

The invention has relation to time-switches for electric-lighting systems, having for its object the accurate regulation and estimation in a simple and ellicient manner of the 1g. 8 is a similar view with Fig. 9 is a diagramhours during which the lamps are kept burii- 4o ing for the protection of both the consumer and the lighting company.

With this ob ect in view theiiivention consists in the novel construction and coinbinations of parts, as hereinafter set forth.

In the accompanyingdrawings, illustrating the invention, the numeral 1 represents an eight-day clock of the usual character, the hour-shaft 2 of which carries hi st thereon the t ime -whecl 3, havin perforations 4 for the insertion of pins 5, w iereby the switch-operating mechanism is set in motion.

In order to provide for shutting. off the lights on Saturday night over Sunday when desired,'l provide the following devices:

ft is a toothed wheel having fourteen teeth and actuated b an inner pin 5 ofthe timewheel 3, where y it is turned one tooth for 1 ened, leaving the wheel 0 free to move up or down to an extent sufiicient to bring the pins 0- thereof into and out of en agement with the vertical end portion d of the trip-lever in the rotation of the trip-wh el.

is a horizontal lever p voted at one end thereof below the toothed wheel n and having 9 at its other end a connection with the bracket p, upon which the trip-wheel is.

' mounted. This lever 51 hits a'n upward-extending intermediate curved arm q, carrying at its upper end an OlltWEld-QflflblflllY-PYO- ject' m g, which normally rests u n the rim 0 t e cam-wheel 0 and holds the ever 9,

bracket p,-and tri -wheel c in raised position l for e agement o the ins of the trip-wheel with t e trip=lever. en, however, Saturday night arrives, the pin. 5, set at the proper time in the time-wheel, will have turned the cam-wheel 0 so that its notch of will come into register with the pin g", which will fall through avity into such notch, the

trip-wheel also is ling, so as to be out of position for engagement of the pins thereof'with the triplev'er.

Inasmuch as raieedi'nto operative position until the camwheel 0 has turned sufficiently to raise the pin q? 'out'of the notch upon the rim of the wheel 0, the lightingcircuit will remain broken for twentg-four hours, in the present case depend ng: the notch wit relation to the teeth of the wheel n. Thus it will be apparent that if one pin 5 is placed in the time-wheel at the point thereof corresponding to the time d e owever, upon the length of sired for the circuit to be broken-say nine oclock the lights will be extinguished each night at that hour, and the same 'pin will close the circuit again at nine oclock every mom ing, ready for the lamps to be lighted at the desired time between nine 9.. m. and nine p. m.

upon the starting of the dvnamos.

If light is desired afterfour a. m. pin is inserted in the timewheel at a second will be closed at this time and broken at nine a. m. and closed againpt'ninep. m., each in tb circuit every may be regulated as desired pins at the proper and no cha the proper point, ask-before stated, and thus the circuit closing or breakiing) twe ,jve hours. So, it ,w lle seen, the li htihghoura '9 laces in the time-whee e need e made in the location of the pins until a change in the lighting hours i is desired. ing the day, a in may be set in the timewheel to closet e circuit it, say, i

a. m. and another pin 'set at, say three oclock or anv other time during the day the trip-wheel will, not be when thecirEuit is to be broken and the lights extinguished, The wiringconnections will now be described. a.

Three bindings sts are shown, 11 and b" opposite each ot er and between them a third binding-post 6', ha connection at b with the pivot of the switc -lever.

In wiring for incandescent lamps or any other circuit to be left open one side wire of the circuit is cut and the terminals connected are somew at different. In this case one side wire of the circuit is cut and the terminal next to the lampsconnected with bindingpost b and the other terminal of the circuit connected with binding-post b. A shortcircuit' wire a: is also oonn'ected'with the opposite indi -post b and leadstotheouter wire 313i the circuit, as shownin Fi 10 of the wings. In this manner, w e the switch-lever a 15 in contact with bindin -post 6, the circuit throughthe lamps willbe c oeed, and when the lever is in contact with binding-post b the main circuit will be broken If the lights "are also desired durfive o'clockl a with binding-post b or b and the intermediate post b.
